I have Firefox home with a search engine as home page, but since the update to 89, when I try to type into the search box, it jumps to the address bar. This is very annoying. Can it be fixed? I do not want to use the address bar this way. I found a help that said to open the application menu and click "customize" but there is no "customize" option there. In the attached photo, I clicked in the search box to place the cursor there, but as soon as I began typing, it jumped to the address bar. This has never happened to me before in the 15 years I have used Firefox. I am a recent convert to Linux (about 1 year now) and am using Mint 19.3, Cinnamon 4.4.8, if that makes a difference.
